Might be there...
If you still feel that you need to see the Tool-tips, I suggest that you just move quickly to the Option bar without hovering over the Tabs; or you could disable the Open as Tabs feature.
Vid of tooltip behavior

Please note: I'm purposely stopping on the tab in the video to force it to show. Most of the time I've just inadvertently paused on the tab while on my way to access an option on one of the bars.
I feel in this case things like turning off tabs or moving the option bar aren't worth the impact on my workflow (which I'm still constantly experimenting with!) than simply moving my mouse just a little further to make the tooltip disappear.
But hopefully someone from Adobe will see this as something to tweak for a future udpate!
